About this unit
Pre-owned 2012 Prolec GE step-up unit described as a spare, with a reconnectable 240 or 120 kV winding; the posted plate is an approval drawing, so final serial and test values need unit records. Location, price and a technical package come with a quote, and the dealer says listings are subject to prior sale. Another broker, J&J Transformers, offers the same unit as brand new and never energized, so ask which is right.
